当前,国民经济正在持续、稳定、健康发展,我国的改革开放和现代化建设也进入了一个崭新的阶段,这对铁路客货运输不断提出新的要求。本文根据1997年国家投入产出表的部分计算结果,构造合理的数学模型,对铁路客货运量发展作一个比较系统的预测。
At present, the national economy is undergoing sustained, steady, and healthy development. China’s reform and opening up as well as its modernization drive have also entered a brand-new stage. This constantly puts forward new requirements on the railway passenger and freight transport. Based on the partial results of the national input-output table in 1997, this paper constructs a reasonable mathematical model to make a more systematic prediction of the development of railway passenger and freight traffic volume.
